public class UrlMapper<T>
extends Object

Url mapping Mapping specification In the web application deployment descriptor, the following syntax is used to define the mapping: ■ A string starting with the '/' character and ending with the '/*' suffix is used for path matching. ■ The string starting with '*.' is used for extension mapping. ■ The empty string "" is a special URL pattern that maps exactly to the context root of the application, http://host:port/context-root/ Request form. In this case, the path information is'/' and the servlet path and context path are empty strings (" "). ■ A string containing only the "/" character represents the applied "default" servlet. In this case, the servlet path is the request URL minus The following path and path information is null。 ■ So other strings are used only for exact matches。 Deployment will fail if a valid web.xml (after merging information from fragments and annotations) contains arbitrary url-patterns mapped to multiple servlets. Sample mapping set Look at the following set of mappings： Table 12-1 sample mapping set Path Pattern Servlet /foo/bar/* servlet1 /baz/* servlet2 /catalog servlet3 *.bop servlet4 Will produce the following behavior： Table 12-2. The incoming path is applied to the sample map Incoming Path Servlet Handling Request /foo/bar/index.html servlet1 /foo/bar/index.bop servlet1 /baz servlet2 /baz/index.html servlet2 /catalog servlet3 /catalog/index.html “default” servlet /catalog/racecar.bop servlet4 /index.bop servlet4 Note that in the case of /catalog/index.html and /catalog/racecar.bop, the servlet mapped to "/catalog" is not used because it is not an exact match
